Professor James Calder is an internationally recognised foot and ankle surgeon. He works with elite athletes and major sports organisations worldwide. He is a professor at Imperial College and co-founder of Fortius Clinic. He has held leadership roles in major orthopaedic societies. His research focuses on tendon, cartilage, and sports injuries.
During the COVID-19 pandemic, James was appointed clinical lead in setting up the NHS Nightingale Hospital London, he chaired the DCMS committee on the return of elite sport, and he has been consultant advisor to UK Health Security Agency for elite sports and performing arts since 2020. He has also chaired the expert group behind the UK Concussion Guidelines for grassroots sport. James was appointed OBE in the 2021 New Year Honours for services to sport and exercise.
In December 2025 the High Court found him liable in negligence in Ebanks-Blake v Calder [2025] EWHC 3327 (KB), over an ankle arthroscopy he performed in 2013 on the former Premier League footballer Sylvan Ebanks-Blake. Having found the experience humbling, James hopes that none of his peers find themselves in the same position, which is what prompted this workshop.
